Reviews for the Lenovo IdeaPad Y50-70-59441231
Model upgrade. Despite its slim build, there is plenty of computing power in Lenovo's gaming laptop. The combination of powerful hardware, 4K screen, and decent connectivity is to make potential buyers curious.

Both notebooks are very good, they have great screens, CPU and GPU performance. They both feature quality build and high specs, but have very different designs, both looking very good. With very similar specs the notebooks produced nearly identical results on our tests and benchmarks, even though Y50’s CPU has some throttling issues.

Model: The Lenovo IdeaPad Y50 Notebook is a gaming laptop with features that would excite enthusiasts. Firstly, there is a highly capable fourth gen 2.5 GHz Intel Core i7 processor. Next, the RAM onboard is 8 GB DDR and upgradable to 16 GB as there are two slots available. The screen has a size of 15.6” and a resolution of 3840 x 2160 pixels. To churn out that much pixels, a GeForce GTX 960M with dedicated 4 GB DDR5 VRAM is used. A Samsung SSD with a capacity of 512 GB is used for storage and the operating system is Windows 8.1.
The keyboard on this IdeaPad features a red backlight, which makes typing and gaming in the dark easy. As for the battery, the 4 cell battery can last up to 4 hours on regular Wi-Fi use. There are three USB ports on this notebook, whereas two of them are USB 3.0 ports. Besides that, there are an HDMI out, a Multi Card slot and also a Kensington lock for security. With the battery plugged in, this notebook only weighs in at 2.4 kg, which is relatively light considering the display size. As a verdict, this gaming notebook sets its self apart from the rest with its 4K display and the ability to play the latest game titles at high quality.
NVIDIA GeForce GTX 960M: Upper mid-range graphics card of the GeForce GTX 900M series.
Modern games should be playable with these graphics cards at low settings and resolutions. Casual gamers may be happy with these cards.

Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.
4710HQ: Haswell-based quad-core processor clocked at 2.5 GHz with Turbo Boost support up to 3.5 GHz. Offers an integrated HD Graphics 4600 GPU and a dual channel DDR3 memory controller.» Further information can be found in our Comparison of Mobile Processsors.
